CELLCASE MACHINE.

To all 'whom it 'may concern.'

Be it known that I, HARVEY SEGUR, a vcitizen of the United States,.residing at Chi'- cago, in the county of Cook and State of Illinois,have invented a certain new and useful Improvement in Cell-CaseMachines, of which the following is a full, clear, con` cise, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to cell-case machines and has to do moreparticularly with the type of machine arranged for making cell cases orfillers for egg crates, although, of course, not limited thereto. One ofthe features of my invention is the provision of mechanism adapted forconstructing the fillers with laterally extending flaps or flangespreferably on two of the outer strips, thereby providing a moreeffective liller having various advantages.

In machines for making cell cases or fillers as heretofore used` so faras I am aware, longitudinali and transverse flat strips have been usedand as a sufficient clearance had to be provided so as to permit ofready insertion of the lillers in the boxes, the fillers did not packtight in the boxes. Tliis permitted of a shifting of the entire fillerin the box and resulted in a shifting or shaking of each entire layer ofeggs in the box.

In order to make. a flanged cell case which overcomes thesedisadvantages I have provided -certain improvements whereby the cellcase is built up as heretofore with transverse and longitudinal strips,but as it is 'passed through the machine two'of the outside strips areprovided with a laterally extending liange preferably formed up as partof and integral with the outside strips.

To this end I preferablypass the straw board to where the fillers aremade through various steps, first preferably *wetting it along the linewhere the flange is creased or bent over and then bending the 'flangepreferably before the transverse and longitudinal strips are assembled.

For a better understanding of my invention reference is to be had ,tothe, accompanying drawings in which- Fig. 1 is a side elevation givingthe general outline of a cell case machine having my invention appliedthereto Fig. 2 is a. top plan view of the machine shown in Fig. 1 butwith feed Fand other par-ts removed;

Taking up the detail construction of the. preferred form of myvinvention as illustrated herein, I have shown it in Conjunction with awell known type of cell case machine of the character shown in thepatten to Swift #622,403, dated April 4, 1899, a side view of which isshown in general outline in Fig. 1. 'The machine includes the usualframe having a maindrive shaft 15 connected throu, z;h'a` suitableclutch-mech- .so strips together with the driving'mechanism anism 16 andgeared to the eccentric shaft 17. The eccentric shaft is connected bymeans of the crank 18 and drive rod 19 to the slitter roll mechanismoperated by the usualintermittent driving mechanism A. The side plate 20of the slitter driving mechanism to which the rod 19 is attached, isalso connected by means of the cam shaft drive rod 21 so as toreciprocate the plate 22 on the cam shaft 23 and intermittently advancethe circular cam-24 to operate the shear mechanism B. Feed rollmechanism C is also provided, this being shown more in detail in Fig. 5and arranged to feed the longitudinal strips of the cell case forwardlyto receive the transverse strips and to the shear where the completesect-ion is cut off.

The usual feed roll mechanism F and cut-off shears for the transversestrips is also employed although, of course, not shown in detail.

At the right end of Fig. 1 I have shown the paper moistener at D, thisbeing simultaneously controlled with the clutch lever 25 (at left ofFig. 1)-so that when the clutch mechanism is thrown in to operate themachine the moistener is automatically rendered effective. And when theclutch is thrown out to disconnect the machine then the moistener isautomatically rendered ineffective. A

In general the operation of the moistener and bending apparatus is asfollows: The straw-board is fed from the roll as usual but beforereaching the bending and cell case cutting mechanism itis passed throughthe moistener D Where it is moistened on one side on a line where theflange is bent over thereby placing the paper in a state to be foldedwithout breaking th'e libre. The

4paper is then fed on through the flange forming mechanism E and thenonto the punch, slitting rollers, etc.

Now as to the moistener mechanism D and which is shown more in detail inFigs. 1, 2, 3 and f1, this comprises a suitable pan 26 in which themoistening fluid is carried and which. is preferably water. Rotating inthe water pan is a pair ofV rollers 27 having a peripheral rim 28 whichwill take up the water and applylit to the paper 29. This rim 28 ispreferably made of leather and suitably fastened to the roller 2'7. Therolls are carried upon a shaft`30 so that they will freely rotate bycontact with the npaper as it passes over the roller. A cover 31 isplaced over the top of the water tank and has an opening throu h whichthe roller extends as indicated in ig. 3. The cover 31 is pivotallysupported at 34 so that it may be lifted up and thereby raise the paper29 out of contact with the moistener roll. I preferably operate thecover 31 by means of a crank 32 so that 'as the crank is reciprocatedone way or the other the cover is raised and lowered. The crank ispreferably controlled by the clutch lever 25 of `the main machine, andto this endis con- A 1, 'that is with the clutch out, the moistener isrendered ineffective. When the clutch lever 25 is thrown to the left inFig. 1, the main machine is thrown into operation and the moistenercover 31 lowered so as to bring the paper 29 into contact with themoistener roll.

This automatic operation of the moistener is brought about to positivelyprevent the paper from soaking up the water when the machine is stopped.VIn order to keep the paper against the moistener rollers I positionweighted rollers 35, one above each moistening roll, the shaft 35 forthe weighted rollers being vertically slidable in the end brackets 37. Ialso apply Weighting block 36 above the paper before it enters themoistener so as to flatten it.

Thus it will'be seen that as the paper 29 is drawn through the moistenera narrow strip along its under side is moistened by the application ofwater thereto-from the eripheral edge of the moistener roll. An it isalong this moistened line that the sheet is bent or turned up. to formthe flange.

Now as to the mechanism for bending or Hanging the paper, I provide aguide along each edge the first portion of which is shown more in detailin Fig. 6 and consists of a c bent up edge 38 curved as indicated inFig.

6 and against which the presser block 39 rests. The block 39 is formedso as to lit the curve of the plate 38 but with sufficient clearance topermit the paper 29 to pass therethrough. It will be noted from Fig. 6that as the paper enters the forming devices 38-39 it is flat, butgradually curvesup into an angular position as indicated at the right orsectional end of Fig. 6. The paper then passes on into the section ofthe formerl indicated in Fig. 7, passing under the curved member 40where it is gradually bent over onto itself as indicated at\t-he rightor sectional end of Fig. 7. Thisnal bending of the paper as indicated inFig. 7, is so as lto give a more permanent set to the flange in that itstrains the paper so that when it finally passes through the machineinto the linished filler it has a slight downward bend so that it may bemore readily pressed up flat against the sides and form a more compactpackage for shipping. It is to be understood that in shipping such casesthe sides are squeezed to ether into a compact fiat package with t eflange 29 folded against the sidev of theliller.

The paper... then passes on under the weighting or pressing roller 41and then on through the gradually receding curved plate 42 where theflange is permitted to again .resume an upright or right angularposit1on before passing under the punch and through the slitterrollers.At the curved member 42 I also provide a component member 43 so that thepaper is more positively guided into its upright position as it passesover the die 44.

The sheet of paper with its up-turned flanges 29 then continues onthrough the slitter roll mechanism G (Fig. 2) where it is cut intostrips before being turned and passed into the feed roll mechanism C.

As to the slitter roll mechanism G, this is constructed so as to takethe flanged sheet and cut it into strips and to this end I provide aclearance slot 46, as shown in Fi 2, and more clearly in .the enlargedsection iig. 11. Thus, the sheet 29 is drawn through the slitterrolls'without unbending the anged sides 29.

After the slitting of the sheet at G the cut strips are fed between thevertically disposed feed roller mechanism C, the various strips beingturned over between the rolls as indicated by the curved lines in Fig.2.

My present machine differs from those heretofore used however, in thatthe outer longitudinal strips have flanges formed thereon which arepassed through the lfeed roll mechanism. In order to take care of theflanged strips I provide a new roller construction, making the outerrolls 47 of a sufiicient diameter with a clearance underneath at 47 totake the flanged strip. I also provide a guide for the outer stripsbefore they enter the feed roll mechanism so as to suitably guide theflanged strips into the rollers and preserve the flange. To this end Iuse sheet metal members 48 gradually curved so as to receive the stripwithout distorting the same.

Y After Vthe longitudinal strips 29 are punched, flanged and slittedthey are advanced to receive the transverse strips from the transversemechanism F in the usual manner and then the completed cell case issevered by the shearing mechanism shown more in detail in Figs. 8, 9 and10. Y

In order to severboth the straight and flanged longitudinal stripswithout distorting or disfiguring the flanges I provide a peculiarshearing devicey 'aving both straight and4 angular shears. The straightshear blades are indicated at 49 in-Fig. 8 and the angular shears at 50,the latter being such that the flanged strip is passed therethrough andthen severed at the proper time without affecting the flange. The shear,which is of the multiple type, has the movable blades connected to thecross bar 51 which is connected by a link 52 to the shear operatinglever 53. This lever carries a. roller 54 travelling in the groove 55 inthe cam24xedtothecamshaft23. Therm:

' be readiy slot is such, and the cam 24 is so rotated that the shearsare operated each time a cell case is completed.

After the case is severed it is removed from the machine by the operatorand folded dup into a compact form with the flanges folded down againstthe side so that it may packed into a more compact space and the angesheld against the sides. Then when the case is opened and put into thecrate the resiliency of the paper causes the flange to spring outwardlysubstantially to a right angle before it is placed down in the crate.
